On a fruit farm 1/3 of the trees are apple trees and 1/5 are lemon trees. The rest are fig trees. There are 90 trees in all.

Vaselesa [24]

Answer:

I'm not sure what the question was but I've worked out all the three types of trees

Step-by-step explanation:

⅓ + ⅕ = 8/15 because:

×5 ×3

5/15 + 3/15 = 8/15

therefore 7/15 is fig trees

90÷15 =6

6×5 = 30 apple trees

6×3 = 18 lemon trees

6×7 = 42 fig trees

What is h(-2) equal to? h(a) = a+10/4 h(-2) – [1]

Veseljchak [2.6K]

For this case we have a function of the form:

$y = h (a)$

Where:

$h (a) = \frac {a + 10} {4}$

We must find the value of the function when $a = -2$ . Substituting:

$h (-2) = \frac {-2 + 10} {4}\\h (-2) = \frac {8} {4}\\h (-2) = 2$

Thus, the value of the function is 2 when $a = -2$

Answer:

$h (-2) = 2$
